Point taken. But, the springs, be they coilovers, leafs, or transverse should not be considered a chassis tuning item... They should only be correctly sized and rated to support the weight of the car. The tuning on coilovers comes in the shock valving and adjustments, the spring part of it just supports the weight. The items I would be concerned with are the bars or rod ends (or hairpins) snapping with the additional bite from slicks. Good shocks valved correctly will do more for traction with any kind of suspension. Nothing wrong with leaving the transverse spring, just make sure the parts that will have to withstand the torque transfer are up to the task!!!!

Most altereds and diggers runs solid mounted rears. They work ok on a good track, but with decent power the cars tend to unhook and buzz the tires once you're off the sticky part of the track... Very few of the smaller tracks spray anything much further out the 60' to 100'...about the same place where you run out of rubber laid down on the track from the other cars. With less power then the rich kids run, a solid mounted rear works great, ran one myself for 3 years in Top Dragster and Quick 8.... Tire choice was critical for the car, softer compound worked better on tracks with less prep to them. If we were running some place that had a lot of big power cars then we could go to a harder compound, get good bite off the line and still keep the car hooked up from 300' to 600'.
